imaging during one or several cardiac cycles with high
temporal resolution.
TVI controls
TVI assignable controls
2D width
Controls the angular width of the 2D image sector.
Lower scale value
allows greater depth
and lower Nyquist
limit.
Scale
Adjusts the repetition rate of the Doppler pulses transmitted to
acquire the data for color mapping. The Scale value influences
the Nyquist limit (the ability to detect maximal velocity without
color-aliasing).
Baseline
Adjusts the color map to emphasize tissue motion either toward
or away from the probe. Baseline is available in both Live and
Freeze.
Frame rate
Controls the line density. When adjusting frame rate, there is a
trade off between spatial and temporal resolution.
Invert
Enables the color scheme assigned to positive and negative
tissue velocities to be inverted. Invert is available in live and
cine replay.
TSI
Starts TSI mode (see page 188).
Simultaneous
Enables simultaneous display of 2D image and 2D image with
TVI color.
TVI visible
Turns TVI display on/off. When TVI display is turned off the TVI
acquisition is still in turned on and raw-data is still acquired but
remains hidden from the display.
Cineloop (in Freeze only)
Starts cineloop acquisition.
